Bug ID: 159986
Summary: WebBackForwardList's currentIndex could get out of
bounds when filtering items.
Classification: Unclassified
Product: WebKit
Version: Other
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit2
Assignee: webkit-unassigned at lists.webkit.org
Reporter: yongjun_zhang at apple.com
In WebBackForwardList::backForwardListState, if we are filtering multiple items and generating a new BackForwardListState, the new list's currentIndex could get out of bounds. If we restore the new state to a web view, accessing to its currentItem later could lead to a crash.
